Driving power supply for enabling LED lamp to gradually lighten

Abstract

The invention provides a driving power supply for enabling an LED lamp to gradually lighten. The driving power supply for enabling the LED lamp to gradually lighten is characterized in that the driving power supply for enabling the LED lamp to gradually lighten comprises a switch signal detection unit, a central processing unit, an LED gradual-lightening driving unit, a live wire ACL and a zero wire ACN, wherein the live wire ACL and the zero wire ACN are connected with the switch signal detection unit; the switch signal detection unit is separately connected with the LED gradual-lightening driving unit and the central processing unit; an RL6070 chip is arranged in the central processing unit; and an RL6625 chip is arranged in the LED gradual-lightening driving unit, and an interface PWM1on the RL6070 chip is connected with an interface DIM of the RL6625 chip. Compared with the prior art, the driving power supply for enabling the LED lamp to gradually lighten has a reasonable structure, after the switching signal detection unit detects a lamp-turning-on operation signal, the lamp-turning-on operation signal is transmitted to the central processing unit for calculation by a dark gradual-lightening algorithm, and then the output end of the central processing unit controls the LED gradual-lightening driving unit, and a current from small to large is output to drive an LED light source to obtain a gradual-lightening process. Eyes are protected, and lightening comfort is improved.

Description

【Technical field】 [0001] The invention relates to the technical field of power supply circuits, in particular to a driving power supply for gradually brightening an LED lamp. 【Background technique】 [0002] In the prior art, after the LED lamp is connected to the power supply, it can immediately emit light to reach the set value. However, the human eye will have a strong sense of discomfort at this moment, which will cause damage to the human eye. Therefore, it is necessary to propose a method that can make the LED After the lamp is connected to the power supply, it can gradually become brighter, which is beneficial to protect the eyes and improve the comfort of lighting. 【Content of invention】 [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a driving power supply for gradually brightening LED lamps, which aims to solve the technical problems in the prior art such as the damage to human eyes caused...
